+Nuxi provides a few utilities to work with [Nuxt modules](/modules) seamlessly.
+
+## nuxi module add
+
+```bash [Terminal]
+npx nuxi module add <NAME>
+```
+
+Option        | Default          | Description
+-------------------------|-----------------|------------------
+`NAME` | - | The name of the module to install.
+
+The command lets you install [Nuxt modules](/modules) in your application with no manual work.
+
+When running the command, it will:
+- install the module as a dependency using your package manager
+- add it to your [package.json](/docs/guide/directory-structure/package) file
+- update your [`nuxt.config`](/docs/guide/directory-structure/nuxt-config) file
+
+**Example:**
+
+Installing the [`Pinia`](/modules/pinia) module
+```bash [Terminal]
+npx nuxi module add pinia 
+```
+
+## nuxi module search
+
+```bash [Terminal]
+npx nuxi module search <QUERY>
+```
+
+Option        | Default          | Description
+-------------------------|-----------------|------------------
+`QUERY` | - | The name of the module to search for.
+
+The command searches for Nuxt modules matching your query that are compatible with your Nuxt version.
+
+**Example:**
+
+```base [Terminal]
+npx nuxi module search pinia
+```
